Hi all, I'm considering buying the Pana 25 1.4 as my first native prime. I know the cashback offer is on until the end of year in the UK, but I'm also going to Hong Kong end of Jan 2013. At the moment, the price in HK is slightly cheaper than in the UK, with the cashback. My question is: Shall I buy it now with cashback? Is it worth waiting until Boxing day or even January, as there might be sales on the lens? (UK users, do you recall any price drop last year?) Or shall I just get it in Hong Kong in Jan 2013? Thank you!
